9 Claims.

This invention relates to a spool or reel of the type formed of sheetstock and is a continuation in part of my copending application, SerialNo. 190,894, led February 17, 1938, now Patent Number 2,258,580.

The invention has for one of its objects to provide a spool or reelwhich will have unusually strong heads so that when copper wire isreeled upon the spool and heated for annealing, which providesconsiderable expansion because of its greater co-eicient of expansionthan the steel of the spool, the strains exerted will be resisted andthe heads will maintain their shape in planes at right angles to theaxis of the barrel.

Another object of the invention is the provision of a structurewhich-will so support the stresses as to remain concentric whereby topermit of high speed drawing without wobbling or chattering of the spoolon its supports.

Another object of the invention is the provision of a spool having thedesired strength in Ythe head and yet one which will have a -seamlessjoint at the corner where there usually exists a seam between the innersurface of the head and the outer surface of the barrel.

Another object of the invention is to prevent the entry of wire into theseam between the barrel and the flange of the head which contacts theend of the barrel.

Another object of the invention is to seal the steam between the end ofthe barrel and the flange of the head which engages the same at spacedlocations suiciently close to prevent the entry of wire into the same.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims.

It is found ln the use of spools, such as are used for annealing copperwire, that when the loaded spool is heated that the expansion of thecopper wire being greater than the expansion of the steel of the spoolcauses tremendous still different modification of the inven- 10 is afragmental sectional view illustratstill different modification of theinven- 11 is a fragmental sectional View illustratstill differentmodification of the invenstresses to be exerted on the head of the spooland often a warping of the head of the spool and an opening at its jointwith the barrel which allows entrance of the wire; and in order that awire may be drawn at high speeds it is essential that the spool beaccurate and concentric with the center hole, and accordingly I have soconstructed a spool that the strains may be resisted sufliciently toprevent the spool from becoming eccentric or any part moving beyond thetolerance allowed for high speed production; and

'- the following is a more detailed description of the presentembodiment of this invention, illustrating the preferred means by whichthese Iadvantageous results may be accomplished:

With reference to the drawings, I0 designates the barrel of the spooland II the heads of the spool which are formed from a piece of sheetstock, as shown more fully in'Fig. 2, having a central hole, the fiangeI3 extending inwardly about the hole and of a size to abut the end ofthe barrel IIl. The outer portion ofthe sheet stock head is rolled as.at I4 to strengthen the edge thereof. A sleeve I5 snugly engages theinner surface of the ange I3 and the end portion of the barrel so as toextend on either side of the joint I6 formed by the Aabutting of theflange and the end of the barrel. For strengthening of the head thissleeve may extend axially and radially outwardly to provide the plate Ilas shown in Figs. 1 to8, 10 and 11 by reason of the 9 is a fragmentalsectional view illustrat curved portion I3 closely following the arcuateportion I8' between the flange I3 and head II.

In some cases the sleeve I may extend from its other end radiallyinwardly as at I9 into engagement with a center tube 20 as shown inFigs. '1 and 8, while in other instances, the stock may extend radiallyinwardly as at 2| for a short distance then axially outwardly as at 22parallel to the barrel and tube 20 and then radially inwardly again asat 23 and turn back upon itself as at 24 toA engage the tube 20 as inFigs. 10 and 11.

A further reinforcement consisting of a plate I 25 will engage the plateportion I1, span the opening of the head and opening 26 of thereinforcement I'I and engage the center tube 20 by being turned inwardlyas at 21 to extend into engagement with raised abutments 28 spaced aboutthe tube and sheared from the stock thereof as shown in Fig. 2, Whilethe outer end portion 29 of the center tube is rolled out- 'wardly overthe curvature 30 of this reinforcing plate to assist in binding theplate in position. In Figs. 7 and 8 the portion 21 engages the outwardlyextending flange 35 from the portion I9.

In Figs. 1 to 'I the diameter of this reinforcing plate 25 issubstantially the same as the diameter of the reinforcement I1, while inFigs. 8 and 9 this reinforcement plate 25 is of a greater diameter thanthe reinforcement plate I1 and is offset inwardly as at 3| (ses Fig. 8)over the plate I'I so as to contact the head II and extend beneath therolled edge I4 thereof. In Fig. 9 in which there is no plate I1, theplate 25' is substantially in a single plane without this oiset andlikewise extends beneath the rolled edge Il, while in Fig. 11 the outerplate is omitted.

Two particular types of welding are illustrated for securing the partsin assembled relation above referred to. In one instance a continuousresistance seam weld, designated 32, may be provided as illustrated inFigs. 1 to 4 to secure the parts at the joints I6 together. In Figs. 5and 6 a spot weld is utilized for this purpose, each of the spots ofwhich is designated 33 and is spaced at various locations along the seamI6 for securing the parts together.- Bothof these types of welds, oreither one, may occur in the various modifications which I have shown inwhich the flange I3 of the head II is secured to the end of the barrelin abutting relation, while the sleeve I5 is secured to the flange I3and also to the end portion of the barrel III. Thus, this weld in thislocation secures three parts in the fixed relation which they assume.The weld while being at the seam and bridging the same also is by reasonof its width located on either side of the seam and in some cases, as inFig. 12, the spots 31 are even spaced from the seam I6 on either sidethereof in staggered relation or these welds on either side of the seammight be continuous.

In the situations where the plate I1 abuts the outer surface of the headII, a spot weld 34, or in some instances a continuous seam weld, isprovided to secure these two parts in assembled relation at variouslocations about the head while a similar spot or continuous seam weldwhich may be provided at the same time where the reinforcement '25 alsooccurs, serves to secure this reinforcement to the reinforcement I I asappears in Figs. 1, 4, 5, 7, and 10 and directly to the head as shown inFigs. 9 and 11.

By reason of the arrangement which I have provided the bridging of theseam I6 either by the continuous weld 32 or by spot weld 33 prevents newire which may be wound on the spool from entering this seam, while atthe same time the Weld secures the three parts in assembled relation andwhile a curved portion of the head at the arc I8' provides no locationat which the wire may enter, even though stresses may occur in the head;in Fig. 12 the abutting of the ends Will be held suiliciently tight bythe welds on either side to prevent entrance of the wire into the seam.'I'he welding of the reinforcements I1 and to the outer surface of thehead strengthens the head and by preventing any possibility of slidingone part on the other provides a head which is substantially as strongas though the head were all of one piece of the three thicknesses of themetal.
